濒危的忠诚

这赛季英超到目前为止,给我印象最深刻的镜头只有一个,就是兰帕德代表曼城攻破老东家切尔西的球门。赛前人们都猜想着这一幕发生的种种后果,但兰帕德进球的那一刻,球场上的蓝军球迷和球员都木然了,连我这个坐存电视机前看球的人都不知道说什么,翻一翻蓝军的球迷论坛,没有辱骂,也没有赞扬,有一个球迷的留言间我心有戚戚：感觉怪怪的。     

The impact of childhood foster care and other out-of-home placement on homeless women and their children

OBJECTIVE: This study compares homeless women who had childhood histories of foster care or other out-of-home placement to those who have not. METHOD: A countywide probability sample of homeless women (n = 179) received structured interviews. RESULTS: One-third of homeless women reported being raised apart from their parents. Among women with children under age 18, most (61.5%) had children who had lived in foster care or other out-of-home placements. Variables associated with homeless mothers' children living in foster care or other out-of-home placements were: Child was school-age, mother was age 35 or older, mother had a current alcohol or drug use disorder, mother experienced childhood sexual abuse, and mother ran away from home (when under age 18). CONCLUSIONS: Parenting is difficult for homeless mothers who may need to place their children with others to facilitate school attendance. Parent-child interaction may be problematic in family shelters where privacy is rare. Thus, programs promoting family preservation for homeless mothers should provide parenting support as well as permanent housing.     

Situational interest impacts college students’physical activity in a design-based bike exergame

Background:Active videogames or exergames have been used as an innovative way to promote physical activity(PA)among various populations.A player’s interest in active videogames is associated with the fun and entertaining nature of the games and may trigger situational interest,thus increasing engagement.The goal of this study was to examine the impact of situational interest dimensions on college students’PA when playing the design-based bike exergame Greedy Rabbit(Vescape,Berlin,Germany).Methods:Sixty undergraduate students(age:20.8±1.3 years,mean±SD,18-25 years old;51.7%males)were recruited from the kinesiology department of a university located in the southern region of Belgium.The participants were assigned to an experimental group(n=41)or a control group(n=19)based on an incremental cycling test.Students in the experimental group engaged in 1 session of Greedy Rabbit(Vescape)while students in the control group engaged in 1 session of a placebo version of Greedy Rabbit(Vescape).The length of the sessions ranged from 24 min to 31 min.Results:Results for the control group indicated that the players’PA metrics(cadence:F(19,360)=1.43,p=0.11;heart rate:F(19.360)=1.16,p=0.29;oxygen consumption:F(19,360)=0.83,p=0.67)were stable during the exergame.Results for the experimental group demonstrated the effects of time on the players’PA metrics and revealed significant associations between the change in the players’situational interest dimensions and PA metrics(cadence:F(19,800)=26.30,p<0.01;heart rate:F(19,800)=19.77,p<0.01;oxygen consumption:F(19,800)=10.04,p<0.01).Conclusion:An approach using a design-based exergame may be a relevant strategy for promoting levels of PA that yields positive health-related outcomes among college students.     

Prosocial and antisocial behavior in sport: the role of coaching style, autonomous vs. controlled motivation, and moral disengagement

The purpose of this study was to examine whether the relationships between contextual factors (i.e., autonomy-supportive vs. controlling coaching style) and person factors (i.e., autonomous vs. controlled motivation) outlined in self-determination theory (SDT) were related to prosocial and antisocial behaviors in sport. We also investigated moral disengagement as a mediator of these relationships. Athletes' (n = 292, M = 19.53 years) responses largely supported our SDT-derived hypotheses. Results indicated that an autonomy-supportive coaching style was associated with prosocial behavior toward teammates; this relationship was mediated by autonomous motivation. Controlled motivation was associated with antisocial behavior toward teammates and antisocial behavior toward opponents, and these two relationships were mediated by moral disengagement. The results provide support for research investigating the effect of autonomy-supportive coaching interventions on athletes' prosocial and antisocial behavior.     

Factors associated with concussion-symptom knowledge and attitudes toward concussion care seeking in a national survey of parents of middle-school children in the US

Background:Developing appropriate concussion prevention and management paradigms in middle school(MS)settings requires understanding parents’general levels of concussion-related knowledge and attitudes.This study examined factors associated with concussion-symptom knowledge and care-seeking attitudes among parents of MS children(aged 10-15 years).Methods:A panel of 1224 randomly selected U.S.residents,aged ≥18 years and identifying as parents of MS children,completed an online questionnaire capturing parental and child characteristics.The parents’concussion-symptom knowledge was measured using 25 questions,with possible answers being“yes”,“maybe”,and“no”.Correct answers earned 2 points,“maybe”answers earned 1 point,and incorrect answers earned 0 point(range:0-50;higher scores=better knowledge).Concussion care-seeking attitudes were also collected using five 7-point scale items(range:5-35;higher scores=more positive attitudes).Multivariable ordinal logistic regression models identified predictors of higher scores.Models met proportional odds assumptions.Adjusted odds ratios(aORs)with 95%confidence intervals(95%CIs)(excluding 1.00)were deemed statistically significant.Results:Median scores were 39(interquartile range:32-44)for symptom knowledge and 32(interquartile range:28-35)for care-seeking attitude.In multivariable models,odds of better symptom knowledge were higher in women vs.men(aOR=2.28;95%CI:1.71-3.05),white/non-Hispanics vs.other racial or ethnic groups(aOR=1.88;95%CI:1.42-2.49),higher parental age(10-year-increase aOR=1.47;95%CI:1.26-1.71),and greater competitiveness(10%-scale-increase aOR=1.24;95%CI:1.13-1.36).Odds of more positive care-seeking attitudes were higher in white/non-Hispanics vs.other racial or ethnic groups(aOR=1.45;95%CI:1.06-1.99)and in older parental age(10-year-increase aOR=1.24;95%CI:1.05-1.47).Conclusion:Characteristics of middle school children’s parents(e.g.,sex,race or ethnicity,age)are associated with their concussion-symptom knowledge and care-seeking attitudes.Parents’variations in concussion knowledge and attitudes warrant tailored concussion education and prevention.     

Decision-making skills and deliberate practice in elite association football referees

We examined sport expertise as a function of role. In study 1, referees were better than players in a video-based decision-making task. This provides evidence that there are role-specific skills within one domain or sport. In study 2, we examined the training activities that could be influential in the development of skills in sports officials. Elite association football (soccer) referees retrospectively reported time spent in and perceptions of training activities for three periods: their first year of formal refereeing, 1998 (before formal training programmes were available), and the current year (2003). This allowed us to examine an area of skill with a limited culture of practice, where performance simulations with direct feedback are usually not feasible. The results showed that referees specialize early and, as they develop, they engage in greater volumes and types of training. Competitive match refereeing is considered a relevant activity for skill acquisition that does not fit Ericsson and colleagues' (1993) original definition of deliberate practice. Our findings indicate that actual performance is a significant activity for skill acquisition and refinement.     

Use of sport-related concussion information sources among parents of United States middle school children

Objective:Parents may use various information sources to obtain information about sport-related concussions(SRC).This study examined SRCrelated information sources used by parents of United States middle school children(age:10-15 years).Methods:A panel of 1083 randomly selected U.S.residents,aged≥18 years and identifying as parents of middle school children,completed an online questionnaire capturing parental and child characteristics,and utilization and perceived trustworthiness of various sour...     

Age and gender differences in children's and adolescents' adaptation to sexual abuse

OBJECTIVE: How children manifest psychological distress following the discovery of sexual abuse requires a better understanding of individual differences in developmental capacities and vulnerabilities. This study examined how age at the time of the abuse discovery and gender of victim are related to psychological distress. METHOD: One hundred and sixty-nine participants (96 children, 73 adolescents) were interviewed within 8 weeks of discovery of the abuse. Multivariate analyses were used to examine how age at discovery, and gender, with abuse characteristics as covariates, were related to shame, attribution style, depression, self-esteem, and traumatic events sequelae. RESULTS: Adolescents compared to children report a higher level of depressive symptoms, negative reactions by others, and lower levels of self-esteem, social support, and sexual anxiety. Girls compared to boys report higher levels of intrusive thoughts, hyperarousal, sexual anxiety, personal vulnerability, and perceiving the world as a dangerous place and lower levels of eroticism. CONCLUSIONS: These findings suggest the importance of considering individual differences in age and gender for understanding patterns of symptom expression. Treatment strategies need to reflect these individual differences in adjustment, such as targeting issues of sexual anxiety for girls and self-esteem for adolescents.
